The CELO series is AUDAC‘s first high-end, slim ceiling speaker
series, consisting of four models which can guarantee an
optimal experience for every situation and application. The
CELO5 is the 5” model of this series. Due to its slim grill design
with a very thin border of only 1 mm and a limited grill depth
which extrudes from the ceiling surface by only 3.2 mm, these
speakers will become nearly invisible when mounted. To make
them blend in even more, the grill can be painted in the same
color as the surrounding surface or an optional black grill
(GLC05/B) will provide seamless integration in dark
environments.
CELO5
High-end 2-way 5" ceiling speaker
The elegant and unobtrusive grill is held in place by means of
powerful neodymium magnets, making assembly and
disassembly very simple but still reliable enough to keep the
grill in place during the complete lifetime of the loudspeaker.
When the grill is removed, it’s clear for anyone to see that the
CELO speakers are made by using only the highest quality
materials, guaranteeing an unsurpassed sound experience.
One 1” aluminum cone tweeter is held in place by an
acoustically optimized arm in front of a 5” aluminum cone
woofer. Together with the crossover network which is made of
high-quality components, this results in true to nature sound
reproduction for a warm and detailed sound with an RMS
power of 50 Watt.
To guarantee a lifetime stability, secure mounting and easy
installation, the loudspeaker connection is made using Gold
plated spring clamp connectors. The mounting of the
loudspeaker into the ceiling should be done by a quick-fixing
mechanism which can be tightened by four screws and the
front grill.

Architects’ and Engineers’ Specifications:
The ceiling mount loudspeaker shall be a 2-way coaxial type, equipped with a 5'' aluminium cone low frequency driver and a 1''
aluminium dome tweeter with neodymium magnet. The tweeter shall be mounted in the centre position of the woofer by means of
an acoustically optimized arm. It shall have an RMS power handling of 50 Watt with a maximum power handling of 100 Watt and the
frequency response (±3 dB) shall range from 70 Hz to 20 kHz. The sensitivity shall be 85 dB when measuring with an input signal of 1
Watt at a distance of 1 meter, while the maximum continuous sound pressure level shall be 102 dB. The nominal dispersion shall be
a 155° conical coverage pattern at -6dB (average 100 Hz - 10 kHz). The loudspeaker shall have an impedance of 8 Ohm and shall
contain a passive built-in crossover network with crossover frequency of 3000 Hz, which is constructed of high-quality components.
The speakers frame and basket shall be constructed as one entity in strong ABS material with a black colour and textured matt
surface finishing. A 4-screw quick-fixing mechanism shall be provided to mount the speaker into a ceiling in a quick and simple way.
The connectivies shall be performed using Gold-Con spring clamp connectors. To make the loudspeaker nearly invisible when
mounted, the speaker shall have a white (RAL9003) grill with a very thin border of 1 mm which extrudes the ceiling surface by only
3.2 mm. This grill shall be constructed of steel which can be painted to make it blend-in with any environment. The assembly and
disassembly of the grill shall be very simple thanks to the neodymium magnets that hold it in place. The speaker shall have a
diameter of 175 mm, a depth of 98 mm and shall not exceed 1 kg. The speaker shall fit in a mounting hole with a cutout diameter of
150 mm and a build-in depth of 95 mm.
